Sustainable biofuels have been considered as a robust option among aviation industries for reducing the carbon footprint in future. One such biofuel is bio-kerosene produced from waste beef tallow that was extracted from discarded wastes found in animal slaughter houses and leather tanneries. This biofuel was produced by thermal cracking of transesterified tallow (tallow based biodiesel) in fractional distillation column for converting it into highly volatile jet fuel. Maximum fat content in the discarded wastes were found to be 75% and the optimum amount of tallow that can be recovered from those wastes was 83%. The extracted tallow was transesterified using ethanol as solvent in a molar ratio of 1:3 whereas potassium hydroxide of 0.5% weight of tallow was taken as base catalyst. Produced biodiesel was thermally cracked in distillation column at a temperature of 120oC producing a yield of 76.8 wt% of tallow based biodiesel taken. The synthesized bio-kerosene was tested for its physicochemical properties in comparison with Jet A1 fuel based upon the ASTM D1655 standards. The combustion and performance study revealed that the static thrust was found to be similar to that of Jet A1 fuel whereas thrust specific fuel consumption and thermal efficiency slightly deviated on varying operating speed. Turbine inlet and exhaust gas temperatures varied accordingly at entry and exit condition depending upon the turbine speed for both fuels. The COX and NOX emissions were also found to be in acceptable range in comparison with Jet A1 fuel.
